IM PROVEMENT IN GAS- H EATERS.

Specification forming part of Letters Patent No. 108,583, dated October 25, 1870.

do hereby declare the nature of the said illvention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement thereof-that is to say:

This invention relates toimproved arrangements in the mode of admitting air to and i-n carrying oft' the products of combustion from gas-stoves, and also in the arrangement and construction of such stoves for heating and Ventilating apartments or buildings. For this purpose I prefer to construct the chamber or body of a stove of thin sheet metal, access being had to the burner or burners by means of a door which can be closed so as to exclude the atmosphere from entering the stove except through the air-supply pipe. The air for supporting combustion enters the lower part ot' the stove by means of a pipe in communication with the chimney flue or pipe, which is also connected by a pipe with the upper part ot' the stove to carry ott' the products of combustion. The combustion of the gas is thus effected in a chamber which has no communication with the atmosphere of the apartment in which the stove is situated. The combined inlet and outlet pipe may be so arranged as to transmit heat to the part of the apartment or building through which it is conducted. Diaphragms are by preference arranged in the upper and lower ends of the stove to distribute the air and products of combustion within the chamber of the stove. The door or other part ofthe body of the stove may be arranged to transmit light through glass or mica panels, if desired.

In order to admit a current of warm airinto the apartment or buildin g for heating and ventilating,-I arrange a pipe in communication with the outer atmosphere, such pipe passing into the lower end of the stove and making a circuit around the upper part of the chamber, terminating with an outlet-opening into the apartment.

In order that my improvements may be most fully understood and readily carried into pracitice, I will proceed to describe the' drawings gas-stove or warming and Ventilating apparavtus arranged according to my invention, in

which the heat is obtained by the combustion of gas.

a is the outer chamber or case, formed of thin sheet metal, supported upon the legs a', and b is the gas-burner, which may be ot' any ordinary form 5 but in the arrangement shown the burner is in the form of' a ring at the end of an arm, b', which is jointed to the top ofthe gas-supply pipe b2, so that it can move to'and lfro thereon. The arm bis connected by a link, b3, to the door ot' thestove, which, ou being opened, draws out the burner to the eXterior of the stove, by which arrangement the gas can be ignited Without risk of its escaping into the chamber of the stove.

c is a coil of pipe formed of thinvsheet metal, entering at the lower and passing out at the upper part of the chamber a, and through this pipe a current of air is conducted from the eX- terior ofthe apartmentor building through the pipe or channel g. By this means a current of freshl warm air is 'constantly supplied to ventilate the interior of the apartment or building. When desired, the outlet to the pipe c may be closed by a cover, c', (indicated in dotted lines,) lto cut olif' the supply of air from the exterior.

In the arrangement shown the air for supporting combustion enters the chamber a by the inlet-pipe la, from the flue fi, exterior of the apartment or building in which the stove is situated, and the products of combustion pass out of the chamber a into the flue i by the outlet-pipe k, an upward and downward current being established in the Hue i. The pipes h and k may pass into an ordinary vopening or entrance to the chimney from the apartment in which the gas-stove is placed, being closed by an iron plate or otherwise. It will thus beV seen that the in terior of the stove is in communication with the chimney only by thepipes h and 7c, being'a closed chamber in other respects. All risk of the gas being blown out by currents of air is prevented by this arrangement. Loss of heat by rapid passage of air through the stove is also prevented.

'i' is a hole for the escape of condensed vapor from the flue t'. The tluez' is only employed where an ordinary chimney is not available.

Zis a door furnished with a panel of glass or mica, which must be closed when the gas is burning, so as to exclude the passage of air through the opening of the door.

m is a diaphragm for distributing the air for supporting combustiomand u is another diaphragm for causing the heated products ot' combustion to circulate within the chamber a.

I will here remark that the current ot' warm air introduced into an apartment through an apparatus constructed as above described may, after warming and Ventilating the room in which the apparatus is placed, be conducted through suitable channelsinto other rooms or parts ot' a building for the purpose ot' warniing and Ventilating the same.

lt will be understood from the foregoing description that the heat from the heated products of combustion ot' gas burning within a chamber, h, Ot' thin sheet metal, (by preference iron,) is transmitted through and radiated from the sides ot' such chamber, a current ot' air passing at the same time from the exterior to the interior ofthe apartment through a pipe or passage, c, or other contrivance of thin sheet metal so arranged within the chamber of the stove as to warm the air passing through it The chamber ot' the stove is ot large cal pacity in relation to the size of the burner to prevent the overheating ot' the metal and to afford a large radiating surface, only suiiicient air being supplied through the combined inlet and outlet flue i to the burner to effect the combustion of the gas. The products of combustion travel very slowly through the chamber a to the combined outlet and inlet pipe or chimney i, the dialihragms m and a at the lower and upper parts of the chamber assisting in producing a steady and even iiow of the air and products of combustionthrough the chamber a.

Having now described the nature of my invention and the means which I employ for carrying the same into operation, I would haveit understood that I do not confine myselt' to the exact form or the details shown and described, which may be greatly varied without departing from the nature of my invention.

. l. The improved arrangement or construe' tion ot' gasstoves for warming and ventilating apartments and buildings, in which the combustion ot' the gas is effected in a closed chamber, a, of thin sheet metal, the interior ot' which chamber has no communication with the atmosphere ofthe room, the air to support the combustion ofthe. gas beingdrawn through a pipe, 7L, from a liuc or chimney, i, into which -the products ot' combustion from the stove are Vitnesses:
